Answer is Homologous.
A diploid individual having two different alleles for a specific trait is called heterozygous. An allele is the alternative form of the same gene. The cells in diploid organisms contain sets of homologous chromosomes, which are paired chromosomes. Each chromosome of a homologous pair has the same genes on the same positions. Although homologous chromosomes have the same genes, they may have different alleles for those genes.
Example: The gene for seed color trait in a pea plant exists in pair. One gene or allele for yellow seed (R) and the other for green seed color (r). A heterozygous plant would contain alleles for seed color (Rr). Gene R is present one chromosome and its allele (r) is present on the other chromosome of the homologous pair.

Answer:
In the resulting offspring the correct proportions are for the genotype 1:1 and for the phenotype 1:1 (first option).
Explanation:
According to Mendel's Laws, the product of the cross between a heterozygous individual and a homozygous recessive for a character will always be a hybrid or recessive offspring as the Punnett square shows on image.
For the character -tall and short- of the pea plant:
Alleles t t
T Tt Tt
t tt tt
<u>For the genotype</u>: probabilities that in the offspring there are hybrid individuals with genotype Tt is 50% and recessive tt 50% .
<u>For the phenotype</u>: the probabilities of tall plants in the offspring are 50%, and 50% short plants.
A 50:50 ratio, for genotype and phenotype, is equivalent to saying that both phenotypic and genotypic ratio is 1:1.
